C. Installation Inspection
(1) Ensure that all requirements of the approved installation data have been carried out and all
components have been correctly installed and secured before the system is energised.
(2) Check that the searchlight has the necessary dimensional clearances in all directions when it is
operational (Figure 9).
(3) Check the radius of swing for the mechanical movement of the searchlight paying particular
attention to areas on the aircraft where the searchlight beam may present a risk due to exposure
to the intense beam from the searchlight.
(4) When installed, operate the searchlight through its range of movement and check that the
searchlight does not point to parts of the aircraft that can be damaged
(5) Perform a function test in accordance with Chapter 5, R.
D. Setup Procedures
CAUTION:
WHERE HARD STOPS ARE SET FOR SAFETY-SPECIFIC REASONS, ENSURE
THAT THE HARD STOP IS CONSIDERED TO PREVENT MOVEMENT INTO THE
EXCLUSION ZONE (REFER CHAPTER 4, K).
NOTE: The factory default settings for the STOW and DEPLOY positions are set within 20° of
the upper elevation and counter clockwise azimuth hard stops.
(1) After removal and reinstallation of the A800 searchlight, the system will require “setup” and
adjustment to ensure it is operating within allowable limits in both azimuth and elevation.
(2) This setup procedure defines the STOW and DEPLOY positions as well as setting the limits of
travel in azimuth and elevation.
(a) STOW provides the optimum position for take-off and landing as well as the best
aerodynamic profile during flight.
(b) DEPLOY positions the searchlight to point in a direction that gives the best initial view when
the lamp is turned on.
(3) The recommended method is to diagrammatically “map” the travel limits and the STOW and
DEPLOY positions. Figure 29 and Figure 30 demonstrate an example of the mapping method with
an explanation following the illustrations.
NOTE: The low speed zones are those positions closest to the end of travel for elevation
and azimuth.
(4) The maximum travel limits (of software) of the A800 searchlight are:
(a) Azimuth rotation:
± 186° (non-continuous)
(b) Elevation rotation:
+ 39° to -101° (standard)
(5) The user travel limits depend on the installed location on the aircraft relative to other equipment
and aircrew positions.
(6) Before use, the operator must identify the Free Travel Zone by a simple mapping process and
then set the STOW and DEPLOY positions. This is followed by setting the azimuth and elevation
hard stops.
